can anyone help me make a Turing program that accepts exactly 15 students marks in (as a percent) and outputs only those marks that are equal to or above the average (mean) mark. The marks, from a text file (in.txt), are retrieved and populated inside a subprogram that must have the signature[color=black][/color][size=12][/size][font=Times New Roman][/font] |

You should think of a few things: How you are going to get and store all of the marks. How you are going to find the average of all of the marks. How you are going to find the marks that are above the average. For this you are going to need basic file input, arrays, basic arithmetic, for loops and if structures. |

The Turing Walkthrough has tutorials for everything you will need. |

I'm not really sure why you are having so much trouble finding the Tutorials. Here's the basics: http://compsci.ca/v3/viewtopic.php?t=9634 Here's if structures: http://compsci.ca/v3/viewtopic.php?t=14656 Here's for loops: http://compsci.ca/v3/viewtopic.php?t=3678 Here's file input: http://compsci.ca/v3/viewtopic.php?t=12972 Here's arrays: http://compsci.ca/v3/viewtopic.php?t=14333 You might also want to refer to question two of the Turing FAQ: http://compsci.ca/v3/viewtopic.php?t=12610 |

Just to clarify, if you're seeking someone to write this for you, you've come to the wrong place. That's the impression I'm getting from your posts, sorry if I'm mistaken. |

I too see this, and am disapproving. Secondly, all the stuff you need is one the Tutorials, you probably didn't even look, just to get someone to write it for you. Which will not happen. This topic will soon be locked if you keep it up. |

Write your own code to the best of your ability, then share it with us if you still seek help, And from there we will help you correct it... |

You guys all basically repeated question two of the Turing FAQ which I linked to. |

var marks: flexible array 1..1 of string var stream:int open: stream,"in.txt",get loop exit when eof(marks) get: stream, marks(upper(marks)) new marks, upper(marks)+1 end loop im stuck i dont know how to get average to pop up to "in.txt" file |

It should be eof (stream) instead of eof (marks). With a for loop you can iterate through all of the elements in the array:
To find the average you need to get the sum of all of the marks and divide by the number of marks. Figure out a way to use variables and the for loop to calculate the average. Remember to close your file when you are done with it:
